' IMPROVEMENT 1N HARROWS.

/Thesl'eule xfre to in these Lette:s Patent an. making part of the same.

`invented certain new and useful Improvements in Harrows; and l dohereby declare that the following is a'full, clear, and exactdescription of the same, and

of the` mode of operation, reference being had to the annexed drawings,making a .part of this specification, and giving a perspective Viewthereof.

My inventioh relates to that class of harrows which is vconnected with atwo-wheeled carriage, on which the driver is seated, and consists of animproved con` structionand arrangement of the several parts, with a viewto simplicity, equilibrium, draught, adjustment, facility of detachmentfrom the carriage, and adaptation for independent use whenevernecessary.

The carriage touny improved barrow consists simply o f a woodenaxle-tree A, carrying a pair of traction-wheels, B B, and of a longtongue, or pole, C, which is extended or prolonged over the harrow, andacross' and behind the axle-tree suiiiciently far to receive aspring-seat, S, for the driver, so as to about balance the overhang infront.

I usnallylap and bolt the pole-extension and axletree together, andsecure and stiien them still further by a pair of angle-braces, b 11;

The hai-row itself consists of ltwo triangular framesections D D, theseveral bars of which are furnished with the ordinary'teeth.

I hinge the twosections together by a hinge, hf, at each end of theinner bars, the straps of said hinges extending over the outer bars, asseen, to serve as tieplates to connect the angles of lthe barrow-framesmore iirmly together'.

A rod, c, bent hook-fashion at the front end, to

l connect with the draught-'chain (Z, and nutted, or fitted with key, orcheck-pin behind the back hinge, does duty as hinge-pivot and draw-bar.

For the purpose of using a short draughtchain, and yet approximate tothe true line of draught, I usually employ a long bracing-staple, e,under the pole, to which I hook the chain el; and I secure the hind endof the harrow from lateral swaying by means of a staychain, ln, on eachside, hooking into a staple, t', `near the corner of the harrow-fran;es.

vThe chains n should be sufficiently slack to permit a free bearing ofthe harrow on uneven ground, and yet prevent contact with theltraction-wheels.

E represents a grooved pulley carrying a crank-shaft,

chain, G, passing over it, the ends of said chain being furnished withhooks h, which are hooked into the same staples as are the stay-chainsheretofore described.

The hinged sections of the harrow accommodate themselves to allinequalities of the ground, and as they are placed infront of thedriver, and under his eye, heY is enabled to manipulate them with greatease and success by the aid of the geared chain and pulley Gr and E.

Should the teeth-spaces become choked by sod, or other obstruction, thedriverseizes the Winch-handle, and by turning it in the properdirection, revolves the pulley gearing with the chain hooked ,to thechoked section, and tilts it up, which enables it to clear itself; o rthe obstruction may be removed by hand, or othervise, withoutdisrnonnting.

The same manipulation in tilting up the sections, enables the driver tosteer clear of any obstacle in the harrows path, as may be readilyunderstood without further explanation.

The barrow is suspended above the ground, and is secured in suchposition while going to or returning that by hand, land secures the twosections togetherl by means of the free portion of said chain, a shorthitch being taken, first or last, with the draught- `chain d.

In harrowing over l'stumpy or stony ground, where the use of a carriageis inadmissible, the harrow may be readily detached by merelyunhookingthe chains, Vand used alone, in thev common way,'by hitching tothe hooked end of the pivot-rod a. f

I do not claim hinging the ysections of a harrow, nor

.combining therewith a wheel-carriage; but having described myinvention,

What I claim as new, and desire to secure by Letters Patent, isv asfollows:

1.- I claim the arrangement of the extension-pole G and attached seat Swith the carriage-axle and wheels A B, and hinged barrow-sections I) D,constructed, connected, and operated, substantiallyas and for thepurpose specified.

2. I claim, in combination with'a wheel-carriage and hinged sectionalbarrow, the pulley E, crank n, and chain'G, whensaid pulley and crankare elevated in front ofthe drivers seat, and the chain hooked to theharrow-seetions, substantially as and for the uses set forth.
